AceNet Error - Autoregistration failed : gateway already lin

I tried deleting the unit on on AirVantage, and add it again.

but after the initial provisioning, I got this message on AceManager again

“AceNet Error - Autoregistration failed : gateway already linked to an invalid system”

on AirVantage, when go into System, it shown its UNKNOWN. (I’m using a Rogers LTE sim card), is that not supported?
